Bad for the brain: Support for cognitive functions in old age

I. Cognitive changes in old age: review and understanding of the problem

As the human, the human brain undergoes a number of changes that can affect cognitive functions. These changes vary from lungs, which do not have a significant impact on everyday life, to more serious, leading to cognitive impairment and dementia. Understanding these changes is the first step to develop strategies for maintaining cognitive health in old age.

A. Neurobiological changes associated with aging:

  1. Reducing the volume of the brain: With age, there is a gradual decrease in the volume of the brain, especially in areas responsible for memory and training, such as hippocampus and prefrontal bark. This reduction in volume is associated with the loss of neurons and a reduction in synaptic connections.

  2. Reducing neurotransmissance: The effectiveness of neurotransmitters, such as acetylcholine, dopamine and serotonin, decreases with age. These neurotransmitters play an important role in cognitive processes, such as memory, attention and mood.

  3. Accumulation of plaques and balls: With aging, amyloid plaques and neurofibrillar balls can accumulate in the brain, which are pathological signs of Alzheimer’s disease. These structures disrupt the normal function of neurons and lead to their death.

  4. Reducing cerebral blood flow: With age, the blood flow in the brain may decrease, which leads to a decrease in oxygen and nutrients to neurons. This can affect cognitive functions and increase the risk of stroke.

  5. Inflammation: Chronic inflammation in the brain is associated with a cognitive decrease and neurodegenerative diseases. With age, inflammatory processes can intensify by aggravating neurons damage.

B. Cognitive functions subject to changes with age:

  1. Memory: With age, a decrease in short -term memory, working memory and episodic memory (memory of events) is often observed. Removing new information and extracting old information can become more difficult.

  2. Attention: Attention can become less stable and less capable of switching between tasks. It can be more difficult to concentrate and ignore distracting factors.

  3. Information processing speed: The speed with which the brain processes information slows down with age. This can affect the ability to quickly respond and make decisions.

  4. Executive functions: Executive functions, such as planning, making decisions and solving problems, can deteriorate with age. This can affect the ability to organize and perform tasks.

  5. Language: With age, difficulties can arise with the selection of words and an understanding of complex language constructions.

C. Risk factors of cognitive decline:

  1. Age: Age is the main risk factor for cognitive decline.

  2. Genetics: A genetic predisposition plays a role in the development of neurodegenerative diseases, such as Alzheimer’s disease.

  3. Education: A higher level of education is associated with the best cognitive function in old age.

  4. Cardiovascular diseases: High blood pressure, high cholesterol and other cardiovascular diseases increase the risk of cognitive decline.

  5. Diabetes: Type 2 diabetes is associated with an increased risk of Alzheimer’s disease and other forms of dementia.

  6. Obesity: Obesity in middle age increases the risk of cognitive decline in old age.

  7. Smoking: Smoking is associated with an increased risk of cognitive decline and dementia.

  8. Excessive drinking: Excessive alcohol consumption can damage the brain and lead to cognitive impairment.

  9. Hodo-brain injuries: Hodo-brain injuries, especially repeated ones, can increase the risk of cognitive decline.

  10. Lack of physical activity: The lack of physical activity is associated with an increased risk of cognitive decline.

  11. Social isolation: Social isolation and loneliness can negatively affect cognitive functions.

II. Bad for the brain: action mechanisms and scientific data

Bades for the brain, also known as nootropics, are substances that are allegedly improved by cognitive functions, such as memory, attention and training. They act in various ways, including an increase in blood flow to the brain, protecting neurons from damage and improving neurotransmission. It is important to note that the effectiveness and safety of many dietary supplements for the brain have not been fully proved in clinical trials, and additional studies are needed.

A. The main groups of dietary supplements for the brain and their alleged mechanisms of action:

    • Examples: Docosaexaenic acid (DHA) and eicopascentaenoic acid (EPA).
    • Scientific data: Numerous studies have shown that omega-3 fatty acids can improve cognitive functions in older people, especially the memory and speed of information processing. However, the research results are ambiguous, and additional studies are needed.

  3. B vitamins B:

    • The mechanism of action: They play an important role in the metabolism of energy in the brain and the synthesis of neurotransmitters. B vitamins deficiency can lead to cognitive disorders.
    • Examples: Vitamin B12, vitamin B6, folic acid.
    • Scientific data: Studies have shown that the additives of group B vitamins can improve cognitive functions in people with a deficiency of these vitamins. However, in general, evidence of the effectiveness of group B vitamins to improve cognitive functions in people without deficiency is limited.

  4. Plant extracts:

    • The mechanism of action: Many plant extracts contain antioxidants and other compounds that can protect neurons from damage, improve blood flow in the brain and maintain neurotransmission.
    • Examples: Ginkgo biloba, ginseng, Bakop Monier.

      • Ginkgo biloba: Some studies have shown that ginkgo bilobe can improve the memory and speed of information processing in the elderly. However, the research results are ambiguous, and additional studies are needed.
      • Ginseng: Ginseng can improve attention and work memory. However, additional studies are needed to confirm these results.
      • Bakopa Monica: Bakop Monier can improve memory and training. However, additional studies are needed to confirm these results.

  5. Caffeine:

    • The mechanism of action: It stimulates the central nervous system, increasing the vigilance, attention and speed of information processing.
    • Examples: Coffee, tea, energy drinks.
    • Scientific data: Caffeine can improve cognitive functions in the short term. However, the chronic use of caffeine can lead to tolerance and a decrease in the effect.

  6. Creatine:

    • The mechanism of action: Increases energy level in brain cells, improving cognitive functions, especially when performing complex tasks.
    • Examples: Creatine monogidrate.
    • Scientific data: Some studies have shown that creatine can improve the memory and speed of information processing. However, additional studies are needed to confirm these results.

  7. Phosphateidixine:

    • The mechanism of action: It is a component of cell membranes in the brain and plays a role in neurotransmission and signal transmission. It is believed that it improves cognitive functions, maintaining neurons health and improving the connection between them.
    • Examples: Phosphateids.
    • Scientific data: Some studies have shown that phosphatidylserin can improve memory and attention in the elderly. However, additional studies are needed to confirm these results.

  8. Acetyl-L-carnitine:

    • The mechanism of action: Participates in the metabolism of energy in the brain and can protect neurons from damage. It is believed that it improves cognitive functions, supporting neurons and improving the energy metabolism in the brain.
    • Examples: Acetyl-L-carnitine.
    • Scientific data: Some studies have shown that acetyl-L-carnitine can improve memory and attention in the elderly. However, additional studies are needed to confirm these results.
